What does butterfly or dudley nosed mean?

Question

I have a male blue and white rat terrier. I have been looking at breed standards and characteristics of these dogs and in a lot of places ( books, magazines, websites ) it says that a butterfly or dudley nose is a fault but I never see any pictures of what this looks like. Could someone please explain? Thanks!

Answer 1

It is incomplete pigmentation. If yours is still very young, it might still fill in.

Depending on the breed it will vary in the level of severity of the fault. If it is small, or on the non-show side, and he is otherwise very nice, a judge may be willing to overlook it. If it is large and very noticeable, it will be a glaringly obvious fault.

I am generalizing, as I don't know your standard.


Here is a good website about nose pigmentation

Answer 2

A Dudley nose is caused when both genes at the "B" loci are recessive. Basically this means the dog does not have the ability to produce black pigment to the nose, eye lids, foot pads, etc,etc.

Answer 3

HI,
A dudley nose is a pink nose, lose of pigmentation. A butterfly nose is a black or brown nose speckled with pink freckles is what is look like to me.
